Abstract :
A procedure for the design of nearly optimum unconditionally stable phase-lock (PL) demodulators is given. The various noise contributions at threshold are investigated and procedures to reduce the noise due to losses of lock are discussed. Experimental results of a nearly optimum 24-telephone-channel PL demodulator equipped with a particular type of threshold noise compensator are given.
